Application filed June 3, 1887. Serial No. 240,184. (No model.)

To all whom, it may concern.I prefer to make the plunger hollow, as shown, o Be it known that I, FRED HERON, a subject and secured to it is a cross-head, J, which ts of the Queen of Great Britain and Ireland, reover the reduced portion I', and is held in siding at Phoenixville, Chester county, Pennplace by a suitable nut.

I above the manipulator. Vhen it is required only to raise the ingot, the Water under pressure is turned into the cylinder H, forcing the plunger I up, so the fingers K lift the ingot clearvof the feed-rollers. After the ingot is raised clear of the feed-rollers water under pressure is allowed to flow into the cylinder N, and the carriage G can be moved from one side or the other of the frame D, depending upon the positionthat the ingot is to be placed in, and by allowing the water to escape from the cylinder H the plunger I falls, allowing the ingot to again rest on the rollers in its proper position. When an ingot is to be turned, the fingers are moved to a position in vrespect to the ingot, as-shown by dotted lines 2 in Fig. 2-that is, toward one side of the ingot--so that when the plunger I is raised the fingers will tilt the ingot over, as shown also by dotted lines 3, and turn it over on its side.

By the mechanism above described I place the lifting-cylinder and its plunger directly under the work, and not at one side, as is usual in this class of machinery. 2 5 Y, In Fig. 4 I have shown the manipulator provided with two cylinders, dispensing with the guide-rods J. v

`In Fig. 5 I have illustrated a 'cylinder and piston that may be used in place of the cylin- 30' der H and plunger I, if preferred. I claim as my invention-y 1. The combination of the tableof a rollingmill with a manipulator mounted on a suitable carriage and composed of a cylinder and 3 5 a plunger, carrying fingers situated directly-v under theload to be manipulated, and devices for moving the carriage laterally, all substantially as set forth..

2. The combination of the traversing carriage with a cylinder, H, a cylinder, H', of 4o larger diameter than the cylinder H, and a plunger, I, carrying the operating-fingers K, the said plunger having stops to limit its movement, substantially as set forth.

3. The combination of the traversing carriage with cylinder, the plunger carrying a cross-head, J, provided with suitable fingers, K, substantially as and for the purpose set forth.

4. The combination of the traversing carriage, cylinderl H, plunger having cross-head, and fingers K, With guide-rods J J for the cross-head, all substantially as specified.

5. The combination of thecarriage, the cylinder H, and plunger I, with a stationary cylinder, N, and a piston-rod, M, connected to one side of the carriage to move it transversely, substantially as set forth. 4

6. The combination of the carriage Gr, cylinder H, and the plunger carrying operatingngers, with a stationary cylinder, S, and a feed-pipe, s, for the ycylinder H, adapted to the said cylinder S, all substantially as set forth. Y In testimony whereof I have signed my name to this specification in the presence of two sub- 65 scribing witnesses'.
